As shown in fig. 1, the utility model relates to an implementation mode of a tilting mechanism for two-sided grinding of diamond saw blade, including base 1, arrange removal seat 41 and the drive on base 1 in and remove the electronic jar 42 of seat 41 back-and-forth movement, remove and have a swing arm 43 on the seat 41 and drive swing arm 43 and make wobbling servo motor 44, swing arm 43 is including the supporting piece board 431 that connects gradually, linking arm 432 and bearing disc 433, supporting piece board 431 perpendicular to linking arm 432 and horizontal direction extend forward, the electro-magnet 435 has been inlayed on the terminal surface of supporting piece board 431, the front side terminal surface of supporting piece board 431 has inside sunken U type notch 434.

The working principle is as follows: after the grinding of the upper end surface of the base body on the grinding station 2 on one side of the base 1 is finished, the bearing plate 431 is driven by the electric cylinder 42 to approach the base body, at the moment, the electromagnet 435 is electrified to suck the base body on the lower end surface of the bearing plate 431, the bearing plate 431 realizes 180 degrees positive and negative rotation under the swinging of the servo motor 44, the base body on the bearing plate 431 is overturned to the grinding station 2 on the other side, in the practical use process, the center of the grinding station 2 is provided with a limiting bulge, the center of the base body is provided with a through hole, therefore, when the base body is turned over to the grinding station 2 on the bearing part 431, the through hole of the base body is matched with the limiting bulge on the grinding station 2, at the moment, the electromagnet on the bearing part plate 431 is powered off, the suction to the base body disappears, the base body is pulled away through the displacement of the electric cylinder 42 in the front-back direction, and the base body is reset again to turn over the base body on the previous grinding station 2.

The utility model discloses a servo motor 44 drives 180 positive and negative rotations of swing arm 43, realizes the upset to the base member through swing arm 43, need not artifical upset, improves the upset accuracy, improves work efficiency. An electromagnet 435 is embedded on the end face of the bearing plate 431, the electromagnet 435 is powered on before turning to generate suction to the base body, and after turning is completed, the electromagnet 435 is powered off to facilitate the swing arm 43 to be pulled away from the base body. Here, the servo motor 44, the electric cylinder 42, and the electromagnet 435 are commercially available products, a PLC system is integrated on the turnover mechanism, and an operator programs start-stop and working sequence of the servo motor 44, the electric cylinder 42, and the electromagnet 435, so detailed description and drawings of specific structures of the servo motor 44, the electric cylinder 42, and the electromagnet 435 are omitted.

Importantly, support piece board 431 needs to hold the support base body, therefore support piece board 431 needs the extending direction setting of perpendicular to linking arm 432, and carry out 180 positive derotation swing in-process at support piece board 431, support piece board 431 can produce great rotation inertia force to the grinding station 2 of both sides, can influence base member surface quality, the utility model discloses a swing arm 43 sets up bearing plate 433 at linking arm 432's opposite side, and swing arm 43 carries out positive derotation round swing arm 43's center when rotating, so bearing plate 433 plays the effect of balanced support piece board 431, weakens this rotation inertia force at the rotation in-process, and is more gentle in positive derotation both ends department.

Secondly, the bearing disc 433 is a disc-shaped structure, the extending direction of the bearing disc 433 is the same as the extending direction of the connecting arm 432 and the diameter of the bearing disc 433 is larger than the height of the connecting arm 432, the bearing disc 433 plays a role of balancing the bearing plate 431, the rotational inertia force of the bearing plate 431 to the base body is relatively weakened in the swinging process, if the extending direction of the bearing disc 433 is the same as the extending direction of the bearing plate 431, the resistance of the bearing disc 433 to the bearing plate 431 during the rotating process is the same as the rotational inertia force or even larger than the rotational inertia force of the bearing plate 431, under the driving force of the same servo motor 44, the speed of the bearing plate 431 is gradually reduced when the bearing plate is rotated to two side positions, and the bearing plate is unsmooth when the base body is sucked and then swung to another grinding station, therefore, the design of the utility model to the bearing disc 433 not only weakens the rotational inertia force of the bearing, but also ensures the swing speed and the swing smoothness of the swing arm 43.

As shown in fig. 2, a gear B45 is sleeved on a motor shaft of the servo motor 44, a gear C46 is arranged on a side end face of the connecting arm 432 of the swing arm 43, a gear D47 is arranged between the gear B45 and the gear C46, a gear D47 is arranged on an outer side wall of the servo motor 44, a diameter of the gear D47 is larger than that of the gear B45, the gear D47 is meshed with the gear B45, a diameter of the gear C46 is larger than that of the gear D47, and the gear C46 is meshed with the gear D47. Further, a gear C46 is provided at the center position of the swing arm 43.

The utility model discloses a swing arm 432 needs to realize 180 positive and negative commentaries on classics, gear B45, gear C46, gear D47 plays the effect to swing arm 432 speed reduction, gear B45 drives gear D47 along with servo motor 44's rotation in proper order, gear C46 rotates, and gear C46 is fixed to be set up at swing arm 432's terminal surface, consequently swing arm 432 realizes rotating, can set up servo motor's turned angle about 180 positive and negative commentaries on classics, thereby the combination of three gear realizes swing arm 432's 180 positive and negative stationarity of changeing, wherein about gear B45, gear C46, the rotational speed ratio between gear D47 sets for according to first carousel 21 and second carousel 31's slew velocity.
